Stand Shim Kit - SB Horseshoe Type

The JESEL Stand Shim Kit - SB Horseshoe Type is a precision component designed for adjusting rocker arm stand height in small block Chevy engines. This kit is particularly useful for builders and tuners who need to optimize valve actuation and maintain proper pushrod angles, especially when using higher-lift camshafts or aftermarket rocker arms.

The kit includes three shim thicknesses—0.025 inch, 0.050 inch, and 0.100 inch—allowing for precise adjustments by stacking shims to achieve the desired rocker arm height. JESEL's manufacturing ensures high tolerances for concentricity and flatness, which are crucial for preventing binding and excessive wear on rocker pivot points during high-RPM operation.

Engine builders and custom shops will find this shim kit beneficial for correcting rocker geometry when original factory stands do not align with upgraded components. Proper installation involves measuring valve lash and verifying rocker travel at full lift, ensuring optimal performance under demanding conditions.
